The benefits I would see is that ksh can have multiple worker threads in a single process, which is far more lightweight than multiple processes. The threads can also share data easily without having to resort to files, pipes or shared memory, which are all slow and expensive ways to share information. That's at least the reasons why there are threaded versions of perl and python, and IMO a shell with thread support would even be more lightweight than the former two.
